Well, Jane Seymour was Henry's favorite because she gave him a son, not because he loved her more than his other wives.

You have a really interesting point, and I agree -- they're similar in a lot of ways. Both married brutal men, were outmatched in wits by their female counterparts, gave birth to sons with health issues, died before seeing their children take power, and were basically forgotten by their husbands, both of whom remarried.

However, they divulge in two crucial aspects: Adolin and their deaths. (Adolin is self-explanatory.) Henry VIII was famous for beheading two of his wives, but he did not kill Jane Seymour. Dalinar didn't mean to, but Henry has one on him in this particular circumstance.

So while I agree that Evi and Jane have a lot in common, they differ in the two major ways that set Jane apart from the rest of Henry's wives.
